Specs:

Low Compression: Lowers cylinder pressures, and I want to keep a good dynamic compression ratio when reving the motor to 11,000 or higher. So about 10.5:1 compression ratio.

Really Huge Custom Cam(s): Over Camming the engine will also help to lower the cylinder pressures and also to give the motor the amount of cam it needs to make power past 10,000. The grinds have yet to be determined.

Thick Headgasket: Lowers the compression ratio to allow a less stressful motor. So, I am thinking a custom Cometic head gasket. Thickness has yet to be determined.

Shortes Honda Engine Stroke: I want to do a custom rod, so for instance a GSR motor I believe has a 85mm stroke. Or something. So custom stroke set for like 75mm or so. I will be sacrificing torque but allowing the engine to make space for some revs. Custom piston designs are also coming.

Decking: Deck the head and block as much to keep a dynamic compression ratio of 10.5:1. This will help to raise the compression ratio since a shorter stroke will be used.

Gear Ratios: I want to build a tranny that will help to keep me in my outmost powerband. Like an F1 car. Shorter gears, but much higher revs. Do I think the ratios are possible, sure. But I don't know what do you guys think.

1st 3.8:1

2nd 2.5:1

3rd 2.0:1

4th 1.7:1

5th 1.0:1

Final 4.4:1

What do you guys think of the motor plans? Trash. I understand the fact that the motor will cost a grip and a half but sounds like a decent idea to me.

I'm not asking someone to guess my hp nor 1/4 mile time. Just wondering what people think about the idea of the motor. I can ask that right?

It smells like the **** you take after you finished off 3 Jager Bombs, and 12 Newcastle's and then paid the Cab Driver extra to stop by Taco Bell on the way home so you can get two Grilled Stuffed Burritos with none of that Fiesta Salsa, Rice, or Bean filler, but instead Double Meat, Double Cheese AND Extra Baja sauce and then go home and pass out only to wake up at 7am the next morning and....unless you have a quarter million dollar grant for R&D, pass the pipe.

Sure you can ask.

 

Got a reason why the motor wouldn't work properly as expected?

Yup, you said it.

 

But give me a reason why? Don't just say it's trash.

mmm that sounds tasty

 

sounds like its gonna be a very slow motor.

i dont think you know what youre getting into.

and i make sound like a domestic guy, but theres no replacement for displacement.


9k rpm 2.0 &gt; 10k rpm whatever displ youre tryint to get with a 77mm(b16) stroke

Well I am curious as to why you are dead set on 10.5:1 compression as well as destroking a GSR to 75mm and then throwing the biggest baddest cams you can at it essentially have a modern day sport bike engine in a car chassis. No TQ is not as bad when the vehicle in question weighs &gt;400lbs which you are killing with low compression, no stroke and huge cams.

I'm just trying to figure out WHAT makes you think it's a good idea, other then doing the opposite of what makes power and tq.

Basically you are going to have a 1546cc DOHC VTEC engine with 10.5:1 compression and gigantic cams. Why don't you save yourself some time and go buy a B16A, throw some custom ground cams with outrageous lift and duration specs and see how little it likes it. It sure isn't going to need to rev to 11K.

 

agreed with mr hammond and casey you should do some research... 11k and 77mm sounds like a bullet bike...

 

omg, this has got to be the funniest thread i've ever seen in here.

 

Thank you. I guess because it's never been done. The reason for such a short stroke is so there is no problem with the valves and pistons hitting at 11,000. If I were to have a higher compression say like 12.5:1 or something then at 11,000 rpms the cylinder pressures would be well over 400 psi. The large cam is so the car can make the power at a really high rpm. So figure like this for instance an F1 car has a V8. Most 2.4l motors. It's basically the same concept in a 4cyl.


And believe me I know about the theres no replacement for displacement. But correct me if I am wrong a 2.0 l will blow up eventually with so much compression and reving so high. Eventually the pistons will meet the valves. To avoid that you go shorter to eliminate the problem. Plus it will be purely used for AutoX racing not drag. If it were to be used for drag then I'd be thinking of a 2.7l K20. Hm.

 

Wow, you're special.

Thats why I came hear. To hear some opinions. Not what people had for dinner.

Do you even understand whats going on? Or are you just being the average post ***** idiot since GDD doesnt add to your post count?

 

very special...2.7l k20....not tryin to be a dick or anything if you need help there are tons of posts for all motor builds and peoples experiences with dyno results etc...

 

haha. its going to be slow, and cost as much if not more than a nice 2.0 setup. Its going to wear as quickly revving to 11k. And if all youre doing is auto x, you only need 2 gears anyway. why not just get a b20 with a b16 4.9 fd and call it a day

Well also Sears Point Racing that could use all 5 gears. I know I didn't mention it but it will be there. VIR. So it will be a tid bit more then just AutoX. A b20 with a 4.9 fd will not be a good motor since it tends to not like the higher revs that most of the VTEC (if you will) motors handle.

 

Comparing a 2.8L (not 4) V8 w/ a pneumatic valve train and just take a wild guess at what the compression is and what kind of fuel the engine is run on and the amount of airflow and......well you get the idea.

The prototype Proton engines (3 cylinders of a 3.0L Cosworth V10) were unreliable, near impossible to tune, and were even more impossible to get the power to the ground. Of course it didn't make 30% of the claimed 900+ HP of the Cosworth V10 either, but look at the type of research, development, testing and budget that goes into designing something like that.

Not exactly going to happen with a B-Series engine.

A 2.7l K20 was a joke. But I've seen the all motor builds. None of them were not de-stroked to rev more. I wonder if this happend to the first person who wanted to put an Integra motor into a civic.

 

I think your the only one who wants to de-stroke there engine.

 

You're going to need a custom crank. Grinding on a crank to destroke (if possible) wouldn't be smart at 11k.

Headwork. Will cost a **** ton to make power at 11k.

Custom 1/2 gearset, hope you have a couple grand for that.

Did you just feel like making a big random list?

The block itself cannot handle the revs. The head will be fine. I've seen B20 blocks just go because of mass reving. My buddy had a daily driven B20 making 213 whp. GSR head. The rods (stock) snapped, the bolts were all over the head. I also know that this is just one motor but I'd rather not get involved.
